Dry Granular Spreading in Michigan

8 operators in our directory list dry granular spreading as a service in Michigan. Use the operator grid below to compare credentials, fleet, response time and pricing before reaching out.

Commercial dry granular spreading in Michigan requires three credentials: an FAA Part 107 Remote Pilot Certificate for the pilot, an FAA Part 137 Agricultural Aircraft Operator Certificate for the business, and AE (Aerial Standard) + Core + use categories from Michigan Department of Agriculture and Rural Development (MDARD). Confirm any operator you hire holds all three before any application.

Most Michigan operators book 4 to 6 weeks ahead of peak windows; rate confirmation is contract-bound and operator-specific. In Michigan, dry granular spreading is most often booked for corn, soybeans and orchards, each with its own seasonal window. For one-off jobs during peak demand spikes, supply tightens fast — establishing the operator relationship in the off-season pays off.

Yes for broadcast rates up to about 80 lbs per acre. A DJI Agras T50 with the 80L dry hopper holds enough for 1.0 to 1.5 acres at typical urea rates, and the operator cycles through batteries and hopper refills to keep throughput at 150 to 300 acres per day. Rates above 100 lbs per acre start to make ground spreaders more economical once fields are dry enough for wheels.

Rescue nitrogen is a side-dress urea or UAN application after the V8 to V12 window, when corn is too tall for most ground rigs and spring rains have prevented timely fertilization. Drones solve this because the tall corn no longer obstructs access and field soil moisture does not matter since wheels never touch the ground. Yield response to timely rescue N on deficient corn is 15 to 30 bushels per acre.

Not for pure fertilizer. Urea, potash, gypsum, lime, sulfur and micronutrients are not pesticides and fall outside FAA Part 137. However, granular herbicides (e.g., Aatrex DF) and combination products that contain any EPA-registered pesticide active ingredient do trigger Part 137 and state pesticide applicator licensing.

Application-only rates run $10 to $18 per acre, with bring-your-own-product arrangements standard. All-in rates including product are typically $22 to $40 per acre for cover crop seed or urea. Minimum field size is usually 40 acres, with cover crop seeding often bundled into multi-service contracts at lower net rates.

Yes, and cover crop seeding is the most common dry-hopper use. The same DJI Agras T50 that spreads urea also broadcasts cereal rye, ryegrass, clover and radish seed at 15 to 60 lbs per acre. Many operators run fertilizer spreading during the May through June window and cover crop seeding August through October on the same equipment.
